Vegas Pro 14. Add Intro to video without massively enlarging the file

[bustee]

Hello,

I want to add an intro to a Video in Vegas Pro 14. The "intro" is simply a still Image with some Background Music that I fade out.

This all works fine, but my original Video has about 80MB, the Video with the intro about 220MB.

Is there any way of approximately preserving the size of the original Video while adding an intro screen (not necessarily with Background Music)?

Original Video:

MP4: 83MB
Video: 00:03:47,040, 25,000 fps progressive, 1280x720x12, AVC
Audio: 00:03:47,029, 48.000 Hz; Stereo, AAC

After editing:

MP4: 227MB
Video: 00:03:54,667, 15,000 fps progressive, 1280x720x12, AVC
Audio: 00:03:54,624, 32.000 Hz; Stereo, AAC

As you can see, I already lowered the framerate quite a bit, but still an enormous increase in size.

Is there any way of ading my intro without that much loss? I don't want to lower the Resolution, 15fps is fine, though.

Frame-rate has no influence on file size. But bitrate does. Compare the bitrate in the original with mediainfo to the bitrate in the edit.


Have not used Vegas for a long time but if I remember correctly there is a setting that compiles the new video with the configuration of whatever the first video is as loaded (or it defaults to the settings for a selected profile). So you either load your original video first before editing or you revise the encoding settings to the bitrate of the original that you discovered from the mediainfo step above.

don't change the fps or audio. change the bitrate the encoder uses. filesize = bitrate x time. there are online bitrate calculators you can use. https://www.3ivx.com/support/calculator/index.html

Thanks,

it was as simple as you said. I Changed the Bitrate and now have a Video with 96MB and the same Quality as the original.. Thanks a lot!

You'd retain your original quality (of the main video) if you didn't re-encode, but rather just encoded the intro alone - to the exact specs that the main video already had been - and then subsequently assembled the 2 clips together (using a different editor which facilitates assemblage in a non-reencoding fashion better than your current one).

Doesn't Vegas have a setting not to re-encode if the settings are the same as the first video loaded so only encodes the intro and the dissolve/fade ?


Mind you. If it is the OPs plan to upload the edit to youtube it makes little difference since they will re-encode it again regardless.

There is no smart encoding settings in Vegas for any encoder. Or some checkbox to select it. Years ago and hopefully that feature was not broken - it was automatic if you had DV video loaded and encoding same DV format, DV template, same with HDV video and maybe some other video camcorder formats, not sure. Or sometimes even DVD mpeg worked, where simple VOB loaded for encoding was rendered with mainconcept template without re-encoding, I had to read a value in mediainfo and set bitrate for the same value and of course all values had to match. But in most cases doing this with mpeg2 file would not work anyway.

Not for specific encoders but this has to be enabled
Options => Preferences => General Tab => Checkmark Enable no-recompress rendering => hit apply

It worked / works for certain formats like XDCAM, DV, DVCPROHD ,certain types of AVCHD, certain types of MPEG2, some lossless I-frame VFW video formats (e.g .UT Video)

All the settings have to match up perfectly, and it can be finicky to "convince" it to work. (This for version 13, the newer "Magix" ones might work better...or worse... not sure)



It probably won't work for the OP for "generic" AVC in MP4 container.

Personally, I would do what Cornucopia suggested , render up to and including the transition, then append with another program

That is 100% correct.

However, because I often find myself needing to "smart render" (i.e., no re-encoding for cuts-only edits) using Vegas, I created a simple Excel spreadsheet that imports a Vegas cut list, saved in EDL format, and then, using Excel code, have it spit out command line ffmpeg code to create individual files from each cut. I then reassemble those into a single file, using ffmpeg.

It is a bit of a hassle and a kludge, but it lets me edit using the tool with which I am most familiar, but still get the smart rendering.

I have also done the same thing using VideoRedo and that also works quite well.

??? smart rendering is still a part of vegas pro as of version 16(i use it)

Wow, excellent. I have settled with re-encoding now and frame serving it, having graphical interface for it. Gave up to not re-encode, sort of going the way having rather enough bitrate.

Does it work with some camcorder H.264 videos now?

[johnmeyer]

I just did several Google searches and could find absolutely nothing about Magix having added any smart rendering for h.264, h.265 or any other format other than DV (which was 100% solid); HDV (which worked one time for me); or MPEG-2 (which worked when it felt like it, and if the moon phase was just right).

So exporting the Vegas EDL to something else still looks like the only solution.

Nick Hope came up with a workflow for doing this that involved a Vegas script instead of going through Excel. I can't seem to find it at the moment, although I still have the .cs script hanging around somewhere.
