How can I address the issue of significantly increased file size when uploading a 32-minute short film to Vimeo after switching from H265 to Pro Res or DNXHR to resolve color banding?

I encountered color banding problems while editing a 32-minute film. Shifting from H265 to Pro Res or DNXHR resolved it, but I’m now dealing with the challenge of uploading a massive 156GB file on Vimeo. My PC limits me to DNXHR HQX. I’m seeking a quicker alternative to a 48-hour upload and have explored Handbrake for compression, but quality preservation is crucial.


You can take the following actions to fix the issue of a much larger file size when uploading a 32-minute short clip to Vimeo after changing from H.265 to Pro Res or DNXHR to eliminate color banding:

1. Select the proper codec and settings

H.264 is the recommended codec for Vimeo when posting videos and it is a fantastic option since it achieves the ideal balance between video quality and file size, guaranteeing a fluid viewing experience. You can choose from a variety of quality presets for H.264. Start by thinking about the “High Profile” setting, which frequently offers the ideal fusion of excellence and compatibility.

2. Compression settings adjustment

It may be worthwhile to experiment with compression settings if you’ve been using Pro Res or DNXHR and observed a large increase in file size. Although using lower-quality presets or bitrates can reduce the file size, you should be aware of possible quality trade-offs.
It is all about locating the ideal situation for your unique requirements.

3. Enhancing Resolution

Try significantly lowering the resolution when exporting to H.264 to manage file size while maintaining video quality. Resolutions like 1080p (Full HD) or 720p (HD) work well for online platforms. File sizes may grow significantly with very high resolutions.

4. Observing the compression recommendations of Vimeo

For encoding preferences, Vimeo provides helpful instructions. To make sure your videos appear excellent and comply with the platform’s criteria, they take factors like resolution, bitrate, and codec into account. You may also, achieve the ideal balance between quality and file size by following these rules.

5. Taking into account video editing software

Professional video editing programs like Adobe Media Encoder can be your buddy if you’re looking for fine-grained control. You may discover the ideal balance between file size and video quality by customizing options like bitrate and encoding profiles.

6. Utilizing Expert Video Hosting Services

Professional hosting sites like Vimeo frequently apply their own compression when you submit films so that they are optimized for Internet viewing. Your videos will be web-ready thanks to the additional compression, which also helps keep file sizes in check.

6. Observing and modifying

Watch your posted videos carefully. Never be afraid to adjust your settings if you ever discover problems with size or quality. Delivering a flawless viewing experience requires routine inspection and adjustment.

By keeping these suggestions in mind, you will be able to control file sizes while ensuring that your Vimeo viewers will enjoy watching your movies. Finding the ideal mix for your distinctive material is key.

Got it! If so than, how does bitrate affect video file sizes and quality for online streaming, and how can I determine the optimal bitrate settings?

@lvan Bitrate is a key factor in striking a balance between video quality and file size. Larger files with a greater bitrate often have better quality. Start with platform recommendations, such as Vimeo’s recommendations, to determine the best settings. To reach a wider audience and guarantee quality without buffering, take into account adaptive streaming with several bitrate versions. Finding the ideal balance is crucial for the optimum viewing experience.
