Sony Vegas — render allowing source to adjust frame rate?
I have a bunch of mobile phone videos (different phones), that I want to render to one single video using sony vegas .
Should I check allow source to adjust frame rate when rendering? Or should I rather use a fixed framerate like NTFS? What would give better results?
Would allowing adjustment mean that each videos gets rendered in its original framerate? Means, the resulting one video would change the framerate during playback? And in case, would this be an advantage or disadvantage?
1 Answer 1
I just wrote a nice detailed answer but somehow I deleted the draft. To save time, the simple explanation (EDIT: I haven’t gotten this from experience; I’m just going off what people have told me in the past):
Changing your frame rate to a fixed one produces exactly the same quality as using VFR (allowing the adjust of frame rate).
Checking the allow source to adjust frame rate button varies the frame rate in the rendered video for each source file. That means that if one of your source videos is 30fps and the next one 60, the frame rate will change when the next source video plays (from 30 to 60 in this example). I cannot think of a disadvantage of this, although re-editing the rendered video may be a bit weird (as shown in OSFirstTimer’s YouTube video). Also shown in OSFirstTimer’s video is that most phones record VFR videos but VEGAS Pro usually corrects that.
If you want to enable solid frame rate (Constant frame rate or CFR) follow this simple 2-step procedure:
Find the source video with the highest frame rate
Set your project to that frame rate
I’m new to Stack Exchange, so hope this helps!
@Gyan in the comments says that this is not the case because «outputting a 30 or 60 fps project timeline consisting of a 30 and 60 fps media clip with 30 or 60 fps output frame rate all result in CFR output.»
We all learn something new every day! 🙂
Also I haven’t had a dilemma between CFR and VFR before, I’m just going off what I’ve seen happen to other people!
Проблема, с Sony Vegas и YouTube — рендеринг
Я уже когда-то, с вами уже пытался решить проблему того почему, у меня не получается записывать видео из игр.
Итогом я вообще пришел к тому что, проблема у меня в слабости HDD.
Теперь же, когда я купил новый HDD и запись стабильна как не когда.
И теперь проблема стала ещё сильнее.
и так: Для монтажа и рендеринга. я решил использовать на этот раз Sony Vegas Pro 13 (x64)
и пересмотрел и испробовав энное количество разный подстроек. для примера остановлюсь на таком.
Render settings questions for MainConcept/AVC/AAC (*mp4) in Sony Vegas

I want to render my videos as MainConcept/AVC/AAC (*mp4) using the Customs settings.
Here is the screen capture of the custom settings. I have questions about the items highlighted in red.
What does "Allow source to adjust frame size" and "Allow source to adjust frame rate" mean? What does it do?
For profile, there are two options: Baseline and Main. What do these mean and which do I choose?

ощущение 20 FPS. при установленной 1080/60
Господи помилуй…
Ладно, всё не так страшно. Пройдёмся по пунктам:
1.) В Project Properties нахрен отключи Deinterlace Method на None. У тебя же не чересстрочное видео, а полный кадр!
2.) При рендере через MainConcept выставь Constant Bit Rate и обязательно отключи Allow source to adjust frame rate, это та паскуда, которая делает тебе 20 фпс, если во всём видео есть хоть кусочек, в котором не 60фпс, а допустим 30 или 25.
3.) Когда видео нарезано и закончено, перед рендером нужно сделать ещё один важный шаг. Нужно выбрать ВСЕ куски видео от начала и до конца, открыть параметры у поменять Smart Resample на Disable Resample. 
Все эти нюансы также можно посмотреть в туторе от Макса.
Use Twitter to Promote your Youtube
Twitter is very good place to promote your vlog or Youtube channel. If you don’t have Twitter account to promote your Youtube channel, you can always create one. Also, you can easily grow your followers. Here is post on how to grow your Twitter account to promote your Youtube channel.
In this video, I will be using Sony Vegas Pro 13. But the concept applies to many other video editing software.
Twitter Video Format
In order to get best result, I recommend following video format.
- HD video 720p (1280 x 720) For square video : 1280 x 1280
- 40 fps (frame per second)
- For best result, video should be around 1 minuet long. (Max Time: 2 minutes and 20 seconds )
- File Type: MP4 or MOV
- File Size: Under 1GB recommended
If you video doesn’t have this format, you need to re-render your video.
How to Re-render your video in Sony Vegas Pro 13
1. Import your video you like to upload to Twitter.
Easiest way to import your video is go to EXPLORE TAB, find the video to import, and drag into the timeline.
Or you can go to FILE > IMPORT > MEDIA
2. Change the video properties
Change the video property. You can change the video property by click on VIDEO PROPERTIES button.
Go to VIDEO tab. Start from choosing the HD 720p-50p template. Now change the following setting:
Most important setting is Frame Rate. Change the frame rate to 40.0000.
From this point on, the setting are to make the rending go smooth on Sony Vegas Pro 13.
- Pixel Format: 32-bit floating point (full range)
- View transform: OFF
- Full resolution rendering quality : BEST
- Deinterlace method: NONE
Click OK to finish and save the project.
3. Rendering setting
Now it is time to render. To render, go to FILE and RENDER AS. Start with Rendering Template Internet HD 720p, and click on Customize Template.
Make following changes to rendering setting.
Start with Internet HD 720p tempate.
- Profile: HIGH
- Frame rate: 40.000
- Uncheck “allow source to adjust frame rate”
- Choose “Constant bit rate (bps)” and choose 10,000,000.
Finally, choose “Rending using OpenCL if available” This optional. If your PC supports OpenCL, I recommend you to use it since it render faster and better.
If you are not sure if your PC has OpenCl availbe, you can check it by going to SYSTEM tab and click on Check GPU button.
Once it is done, click OK.
Now give it a file name and RENDER.
4. Upload to Twitter
When the render is done. Try to upload the newly rendered video file again.
If you are continue to have problem with uploading, try using Chrome browser. Chrome browser, somehow, works the best.
