Video export option requests

Your idea

Video export is wonderful enhancement as is, but could be even better.

Short versions

1. In the video export settings, could we please have a selectable frame rate drop down, similar to that for audio bit rate and video resolution.
2. Could we have an option to exclude the opening title

Longer versions

1. In the video export settings, it would be good to have a selectable frame rate drop down, similar to that for audio bit rate and video resolution. The current default, 30 fps is far larger than need for many purposes and gives unnecessarily large file sizes (typical video !). I have been re-coding the video with Handbrake back down to 12 fps. This gives a perfectly good video score for many teaching & learning purposes.

2. Could we have options to exclude the opening title and, maybe, the end credits ? See also node https://musescore.org/en/node/392534 et al. Having the title (3 secs ?) means the actual audio is offset 3 secs into the video.

Problem to be solved

Working on 4 part SATB scores, my workflow is:

1. Export as mp4 to make the video of the score
2. Use Handbrake to reduce frame rate from 30 to 12 fps. This reduces video file size to 20 - 30% of the original
3. Back in Musescore, export the voice parts as mp3 or aac files
4. Use ffmepeg to add the voice part files as additional audio streams in the mp4 file and label each stream with the voice name.

This gives an on-screen video where you can choose what voice part to hear while score plays on-screen.

Having a selectable frame rate in Musescore eliminates step 3 above and save disk/ storage space.

Step 4 is considerably complicated by having to offset all the voice part streams by 3 seconds to match the onscreen video which itself is delayed by the duration of the opening title. Eliminating the title means the individual voice part streams do not need to be offset and plug straight in secondary streams.
