Ideas for additional export dialog features

[kylagit]

OpenShot currently takes a very long time to export videos on my laptop despite being recent and high end with a Ryzen 7 350. It would be nice to have an option which allows you to choose the x264 encoding speed preset in the advanced tab of the export dialog so you can choose the encoding speed to quality per bit ratio you would like.

It would also be nice to see an option to switch to the CRF bitrate mode, which lets you choose a target quality such as CRF 23 which the x264 encoder will maintain across a video by automatically adjusting the bitrate. That means that you will not have to give a video that is mostly still but has some high motion parts a needlessly high bitrate so the high motion parts stay clean.

It would also be nice if there was a custom box which allows you to pass custom parameters to the encoder so you can fine tune it depending on your needs.

Hello @kylagit

Please go to openshot.org/download/#daily and download the v3.5.0-release-candidate build #15536. If you are running Linux or Mac OS, download the AppImage.

There are some improvments in performance to both Export and the size of the *.mp4 it creates.

In Edit | Preferences | Performance you can now enable Hardware Acceleration without having issues while editing. Select an option and click on Test to ensure OpenShot returns a green check mark.

Regarding CRF: Got to openshot.org/user-guide/. In the search field, type Video Settings and press the Enter key. In that section you will find the CRF option to try.

Would to hear back from you with your results. v3.5.0-release-candidate just completed QC testing and is in the process of being release into production, soon.

Also, please provide us the following:

1. Your computer specs (CPU, GPU/RAM, RAM, Hard drive type and free disk space available).
2. What operating system/version you ar running.

Thank you, I will try that tomorrow.

I have a Ryzen 7 AI 350, an RTX 5050 Mobile, 32 GB of RAM, and a 1 TB NVME SSD. I won't know the exact figure until tomorrow however most of the SSD is free.

My OS is Bazzite which is based on Fedora Silverblue, and I am currently running the Flatpak version of 3.3.0

The Flatpak is not supported. Make sure to download the AppImage. Make it executable. It also requires libfuse2 to be installed.

I am a Windows user but I do have several Linux flavors running in my Oracle Virtualbox environment. I do have Fedora 43 and the AppImage runs without any issues.

Update: I forgot to mention that during the Export process, OpenShot now default to CRF exporting. From the Export screen click on the Advanced tab and note that the Bit Rate / Quality: is set to 20 crf

Hello @kylagit Any update?

[kylagit]

I have tried it and it is nice to see a CRF option, however there is no option to switch back to an average bitrate if needed, nor is there the option to adjust encoding speed or enable Blu-ray compatibility which is needed for some TV video players).

Thank you for the FYI @kylagit

Regarding the "...switch back....", are you saying you are unable to manually override? Also, if you could, please include a screenshot so I can see which screen you are talking about.

Regarding Blue Ray. When you click on Export and from the Simple tab, click on All Format for Profile and in the drop down you should see Blu-Ray/AVCHD option. Are you not seeing this? If it is something else, then please provide all details.

Thank you in advance!
