The Quality of Videos Shot on iPhone Varies Based on Sending Method

Have you ever felt that when you send videos shot on your iPhone to friends or family, “it looked nice on my phone, but the quality is bad on the recipient's phone?” In fact, the quality of videos shot on the iPhone can change depending on the app used for sending or the sharing method. In particular, 4K videos or videos shot at high frame rates tend to have larger file sizes, making them automatically compressed when sent. To send videos without degradation, it is important to pass the original file to the recipient without re-compressing it. The main sending methods can be summarized as follows.

Sending Method	Quality	Recommended Use
AirDrop	Easy to maintain original data	Apple users nearby
iCloud Link	Easy to maintain original data	Sharing with non-Apple users
File Transfer Service	Capable of sharing original file	Sharing with Android/PC
Regular LINE Sending	May be compressed	Casual video sharing
Email Attachment	Can attach original file sometimes	Sharing short videos

If prioritizing quality, it is recommended to use methods like AirDrop or file transfer services.

Five Ways to Send Videos from iPhone Without Degradation

Now, here are methods for actually sending videos shot on an iPhone without losing quality.

1. Send via AirDrop

If the recipient is nearby and using Apple products like an iPhone, iPad, or Mac, AirDrop is recommended. AirDrop is a feature that allows direct sharing of photos, videos, and files between Apple devices. Since there’s no need to upload the video to LINE or other platforms, it’s suitable for sharing while maintaining the original quality. Sending Steps

1. Open the "Photos" app on your iPhone
2. Select the video you want to send
3. Tap the share button in the lower left corner of the screen
4. Select "AirDrop"
5. Choose the sending device
6. Once the recipient accepts, the transfer will begin

To use AirDrop, both sending and receiving devices must have Wi-Fi and Bluetooth enabled. If a file format conversion setting appears during sharing, selecting "Current" allows sharing without converting the file format. It can even send large videos like 4K smoothly, making it convenient for passing high-quality videos to someone nearby. However, since AirDrop is fundamentally designed for sharing between Apple products, if you want to send videos to Android phones or Windows PCs, consider using other methods.

2. Send Using an iCloud Link

If the recipient is not nearby, you can also opt to use an iCloud link. An iCloud link allows you to generate a URL for sharing photos and videos, which can be sent to the recipient for downloading. Even if the recipient does not use Apple products, they can view the video from a browser, making it useful for sharing with people at a distance. Sending Steps

1. Open the "Photos" app on your iPhone
2. Select the video you want to share
3. Tap the share button
4. Open the "Options" on the sharing screen
5. Enable "iCloud Link"
6. Create the link and send it to the recipient

The recipient can open the received URL to view or download the video. The validity period for an iCloud link is 30 days. Therefore, if you want to store the video for a long term or keep it available for downloading at all times, be cautious. Also, check the iCloud storage capacity and sharing settings as well.

3. Use a File Transfer Service

If you want to send videos to someone using Android phones or Windows PCs, a file transfer service is advisable. A file transfer service allows you to upload files such as videos and images to the internet and share the generated URL with the recipient. Because it shares the file itself instead of sending it as a post for social media or messaging apps, you can maintain the original quality. Additionally, some services do not require the recipient to install the same app or register an account. For instance, a free file uploader called "UploadF" is available. UploadF allows you to upload files from devices like iPhone or Android and computers. Features of UploadF

• Direct uploads from iPhone or Android
• No account registration required
• Free file sharing
• Can upload up to 100 files at once
• Storage period can be set from 1 day to unlimited (with possible extensions)
• Can share with a password
• Can individually delete unnecessary files

Steps to Send Videos

1. Access UploadF from the iPhone's browser
2. Select the video from the upload screen
3. Set the storage period and password as needed
4. Start the upload
5. Copy the shared URL displayed after the upload is complete
6. Send the URL to the recipient via LINE or email
7. The recipient opens the URL and downloads the video

With this method, sharing can be done with anyone using iPhone, Android, or computers. It is particularly useful when you want to pass videos shot to friends or deliver videos shot for work to clients. Additionally, it allows sharing not only videos but also multiple photos and documents together. If sending videos via messaging apps like LINE causes quality loss, consider uploading the video to UploadF and sharing the URL.

4. Send Videos as Files via LINE

If you commonly use LINE, there’s also an option to use LINE's file sending feature. When sending a video as a normal photo or video from the LINE chat screen, the video may undergo compression or conversion that affects its quality. Thus, there’s a method to send the video not as regular media but as a file. Sending Steps

1. Open the "Photos" app on your iPhone
2. Select the video you want to send
3. Select "Save to Files" from the share button
4. Select where to save the video
5. Open the chat screen with the person you want to send on LINE
6. Select "File" from the "＋" button
7. Select the saved video to send

By sending it as a file instead of a normal video, you may share the original video data without any alterations. However, since the conditions for sending files may vary depending on LINE's specifications and usage environment, it is reassuring to check the quality and size of the downloaded file on the recipient's side after sending. Additionally, if the video file is too large, it may not be sendable.

5. Send via Email or Mail Drop

For short videos, you can also attach the file to an email and send it. If you can attach the video file directly, you can send it without re-compressing it to the recipient. However, typical email services often have size limits for attached files. 4K videos or long videos can easily become large, making it difficult to attach directly to emails. In such cases, utilizing the iPhone's Mail Drop can be helpful. Mail Drop is a feature of Apple’s email system designed to send large files. Sending Steps

1. Open the "Photos" app on your iPhone
2. Select the video you want to send
3. Select "Mail" from the share button
4. Input the recipient and subject
5. Tap the send button
6. If the file is large, utilize Mail Drop for sending

Files sent via Mail Drop must be downloaded by the recipient within 30 days. While this allows for easy sharing through email, for long-term storage or sharing with multiple recipients, consider using file transfer services as well.

Why Does the Quality of Videos Sent via LINE Deteriorate?

The main reason for the decline in quality when sending videos via LINE is the compression process to reduce the file size. Videos shot on an iPhone are often saved in high quality like 4K or 60fps, depending on settings. However, sending them directly can result in large file sizes, which may lead to longer transmission times or increased data usage. Consequently, the service side may compress the video or change the resolution and bitrate. For example, there are such differences:

Item	Before Compression	After Compression Example
Resolution	3840×2160 (4K)	1920×1080 (Full HD)
Frame Rate	60fps	30fps
Bitrate	High	May decrease
File Size	Large	Small

* The above is an example of changes due to compression, and does not mean that LINE will always switch to these settings. In particular, video with fast movements or containing fine text shows a noticeable change in quality due to compression. When editing or preserving videos, it’s essential to choose a method that allows you to share the original file rather than typical video sending.

Points to Check When Sending Videos from iPhone

To maintain video quality while sending, pay attention not only to the sending method but also to the video settings themselves.

Check the Resolution and Frame Rate During Shooting

On iPhone, you can set the resolution and frame rate for the videos you shoot. For instance, capturing in 4K at 60fps can record very smooth video, but in turn, results in larger file sizes. You can check the shooting settings as follows.

1. Open "Settings" on the iPhone
2. Select "Camera"
3. Open "Record Video"
4. Check the resolution and frame rate

If you want to maintain the quality of videos you have already shot, it’s advisable to choose methods that share the original file rather than decreasing the resolution or using compression apps.

Do Not Convert the Video Format Unnecessarily

On iPhone, videos taken might be saved in formats like HEVC (H.265). HEVC offers high compression efficiency but may not be playable on older computers or some video editing software. Therefore, depending on the recipient's playback environment, it may be necessary to convert to a more compatible format. However, converting formats could change the quality due to re-encoding. To prioritize the original quality, it's best to share the original file and check if the recipient can play it.

Keep the Original Video File Intact

Before sending videos, ensure you do not delete the original file. Once a video has been compressed, it is fundamentally impossible to revert it back to high quality. In particular, for videos shot for work or essential events, it is recommended to keep the original data until sharing is complete.

Summary of Methods to Send Videos from iPhone Without Loss

To send videos shot on an iPhone without degradation, it is crucial to choose methods that do not re-compress the video when sending. In summary, the methods introduced are as follows:

• If sending to nearby Apple users, use AirDrop
• If sending to someone far away, use an iCloud link
• If sending to different devices like Android or Windows, use file transfer services
• If wanting to use LINE, consider sending as a file
• For short videos, use email or Mail Drop

Especially when using videos for work or passing on editing materials, be mindful of maintaining not only quality but also factors like resolution and frame rate. Additionally, if you want to send multiple videos or are unsure which device the recipient is using, using a file transfer service can be convenient. Free services like UploadF allow you to upload videos directly from the iPhone and share the generated URL. You can also share photos, documents, and other materials together, so be sure to take advantage of it.
