I will try now. Thanks.

Fred

I still have clients who want DVDs. I have always used Magix Vegas 20 and the Main Concept encoder to make my mpg2 files. But I have found that ffmpeg makes a substantially better mpg2 - smaller files and sharper images from my 4K Canon XF605 camera.

My workflow has become to make a lossless MP4 with Vegas/Voukoder, then run it through ffmpeg with this command:

ffmpeg -i MVI_0023.mp4 -b:v 6000k -colorspace smpte170m -vf "scale=720:480,setdar=16/9" -target ntsc-dvd Sat34.mpg

WIth these parameters, Tsunami's TMPGENC Authoring Works accepts the MPG2 file without re-rendering it, and I get a 2 hour program on a single 4.7GB DVD. (With Main Concept renders at a 8M bitrate, it took 2 disks). The images are truly sharper than with Main Concept.

Is there a way to specify these parameters in Voukoder directly from Vegas?

Thank you everyone. Joe24's settings worked for me. This is a big time saver.

+1 for TMPGENC encoder.

Too simple! Thank you.

Fred

Over the last year or two I have experimented with different settings, which I have saved in the hope that each test would be the ultimate one. Now I have a whole bunch of templates that are not useful. Where do they reside on the hard disk, I would like to delete some of them.

Thank you AVWTP and Joe24. I used the settings in joe24's post, and while I couldn't find a setting for CABAC, it came out that way and TAW was happy. What a timesaver.

Fred

avwtp: Sorry, that was a long layoff.

I use Magix Vegas, not Premiere. Could you please do a screenshot of your Voukoder settings for BluRay in TMPGENC?

Thank you,

Fred

Make sure you don't have the audio tracks muted in Vegas.

avwtp, thank you.

I would like to try both NVENC and X.264. If you would please share the settings for both, I would truly appreciate it.

[edit] I have a 2.5 hour program, so have to set the bitrate properly.

I still have clients who want BluRay disks. I have tried checking the BluRay compatibility box in Voukoder dialog, but even with that set, rendered output is re-rendered by my BR authoring program. I use TMPGENC Authoring Works, version 5.2.6.55. What setting should I use to eliminate the re-rendering?

Thank you in advance.

It appears this is not a Voukoder problem. Over on the Vegas Pro forum a user with a similar camera and similar problem suggested I combine all the mxf files into one with a couple simple scripts. He thinks the issue is a buffer in Vegas Pro.

Another user suggested upping the bitrate.

Both solutions appear to work.

I consider this bug closed.

Thank you

I have been getting a strange error in MP4s rendered with Voukoder. (Before I go any further, I LOVE Voukoder, beautiful images, small files.)

The symptom is a brief pixelated image in the rendered file at the point the timeline transitions from one event to the next one. But it only happens about one time in 10 or 15. In one file, the pixelated frames are from a different part of the timeline. . In one file, this happened at the third transition. In another, at the 12th transition. This error does not occur with Magix MP4 template at the same transition.

The events are Canon MXF files from a Canon XF300, 1920 x 1080, 60p, at 50Mbps. There can be 20 events on a timeline. The events are all butted up against each other, there are no gaps.

There is the video track, and above it 3 other tracks, one with a simple legacy text that says "7 PM" with clear background, one with a single empty event with a timecode running, and one with song titles and performers' names in a Vegas Credit Roll.

VEGAS White balance FX is applied to all events.

Vegas version 18, build 527. Computer AMD Ryzen 3900X 12-core processor at 4GHz not overclocked. 8 GB memory. Source files are on an SSD. Vegas program is on a different SSD. Render output goes on an internal HDD. Running this template with these files, CPU load is over 90% and sometimes hits 100%. NVIDIA GPU is loafing. Windows 10 Pro, OS build 19041.985.

Voukoder version 7, template: "Video: project default, Audio: project default"

"Audio: 0 Hz, 0 Channel

Video: Project Frame Rate, Project Frame Size

Pixel Aspect Ratio: 1.000"

(Note: there is audio in the source and the rendered output, and it is working properly.)
