Audo sync/timing issue with v X9.5

[hEdly]

Hey all
99 people have read this and not a single response. Maybe it's too long

Bottom line up front
I've got the audio delay issue with AVCHD files mixed with other sources.

Is there a post with a solution somewhere?
if not, what are my solutions?
- what setting should I tweak?
Would putting a small pause between the various file types help? Or maybe between chapters?
Does updating to x9 SP4 fix the issue?
What about VS x10; if I purchase that will the issue be resolved?
- If I but x10, will I need to re-purchase the blu-ray authoring?

Now, all the pertinent information...
I take the videos with a Cannon HF M30. Some with our Canon SX50HS (camera) and another Canon point and shoot. We also take videos with my Galaxy S5Activ and my wife's iPhone (both an old 5 and her new 7).

I'm using Corel VS x9.5 (v19.5.0.35) Ultimate. Computer specs on the right. The video card is old and only used because my monitor only as a DVI or HDMI connector and the computer only has VGA or Display port. I just happened to have this old card with the DVI. I bank on the power of the i7 to do the legwork and it's pretty fast.

From the camcorder:
Format: NTSC HDMV
Video Type: H.264, Upper field first
attributes: 24 bits, 1980x1080
Frame rate: 29.970
Data rate: variable (max 1600 kbps

Audio type: dolby digital audio
Attributes: 48000 Hz
Layer: none
Bit rate: 256 kbps

Anyway, I convert the files to blu-ray format (format matching the above). The only reason is so that they show up with the rest of our movies on our HTPC.

I put all the files from the video camera and various other sources into a temp folder and then sort by date. I then merely click and drag them into the VS window.

Then I add in chapter marks and convert to Blu-ray (the project type matches the HFM30 format since that's most of what the videos are). I don't bother with menus or anything fancy. Just the video.

When watching after rendering, I get a 1 to 2 second delay with the audio.

I've read a couple of the posts about this including here:
viewtopic.php?f=1&t=60234
and a couple others that I can't seem to find now that I'm writing this. But none of them had a solution that I could see. I've tried to turn off SmartRender but I think I remember seeing that it's not an option when converting these files; in truth, I can't even find that setting anywhere. I think I saw something about variable bit rates being a bad thing. I tried messing with some of the other settings, but I still can't find a solution. It takes time to render a file long and see the error and I'd like to get some direction before just going off on a wild goose chase.

So what are my solutions?
- what setting should I tweak?
Would putting a small pause between the various file types help? Or maybe between chapters?
Does updating to x9 SP4 fix the issue?
What about VS x10; if I purchase that will the issue be resolved?
- If I but x10, will I need to re-purchase the blu-ray authoring?

Thanks for your time and consideration in advance.

Best regards,

Hi

Sorry to hear you have not had any replies to your post, I guess the lack of replies indicates the lack of ideas we have.

If you are mixing various video formats have you tried using just one type from one camera
Start with your main camera (Cannon HF M30) as far as I can tell those are Bluray Compliant and should not cause any problems.
I have to say I use similar files but do need Smart proxy, just my old pc is a little slow........

Add several of your files to a new project should show the messages to match the properties.
Now go to Share – Choose Same as First Clip and render the project.

Do you have any problems with Audio Sync?

Now add other video from your other video cameras, not Iphones or Galaxy
Repeat the render, do they cause problems.

I would suspect that the Iphones/Galaxy are causing issues as they will / may be using a variable frame rate, You may have to use a video converter to create a more suitable editing format

So how far do you get by rendering separate video types?

So would upgrading to V10 fix the audio/video timing delay.

It's hard enough to find time to take our videos and turn them into something we can send to family around the country. having to do some kind of middle conversion will certainly drive me to using an different brand of software where I can do it in one fell swoop.

So have you bothered to try some of latas suggestions? Why would you think that using other software will work better? There is no magic "one-slick" solution in video work

interogate your video from different sources, use MediInfo/GSpot. Look for variable frame rate, when found convert to fix frame rate.

Sorry it takes so long to reply...life.

Mr Johnny, I don't even know what that means. How does one interrogate from different sources? Do you do this to the final video or the sources? I had to look up with those software do.

Canuck, I originally asked if upgrading to v10 would solve the issue. So why shouldn't I ask that again since the original question wasn't answered.

Life is busy with wife, kid, family, sports (playing, not watching), occupation, house work. I used to code, create web pages, and tinker with computers and the like but I just don't have time any more. If there's a better solution to Corel out there that can handle variable rates better then I'll use it to save time. Heck, I just bought a new computer pre-made because I didn't want to waste the time building one. I have found that family time is just too precious to spend tinkering.

Now, to get back to brass tacks. I did happen to record an event wholly with the camcorder and then turn it into a blu-ray. It appears that there was no sync issues.

As an engineer and someone who's dealt with data analysis, signal processing and even some image processing, it surprises me that 21st century software can't handle it. It ain't rocket surgery. But I'll get off my high horse.

What's more frustrating is that this is a new issue. I've been mixing camcorder and phone videos for several years and it worked with version 9 and then 9.5 until it began crashing during video rendering. Hard crashes...the computer would just shut off in the middle of the process. So I got the new computer and viola, no crashing. But now there's this syncing issue.

So, I guess there's some questions to get over if I want to keep processing the Canon and phone videos
1) what video converter should I use on the phone videos?
- Can that software batch process so that I can keep each video a separate file since they will be interwoven with the Canon videos?
- what format should they be output to?
2) Have people encountered this issue with v10?
3) While I like Corel and the cost to performance ratio is very appealing, is there a software that you all are aware of that can do this without converting first to another format of constant. I'm not sold on Corel, just like I'm not sold on Windows.

Just before I hit submit, I had another thought.
- Can't I open it up in v9.5 and separated out the audio and video tracks?
- Could I see the delay?
- If so, is there a way to re-sync it?
- Can I drag the audio back a bit so the end of the audio track matches the end of the video?
- Would I lose any fidelity by re-rendering if the above works.

Thanks again for all y'alls time.

Hi hEdly

Use MedioaInfo or GSpot to determine if the source files use variable frame rates, if so, use another program (Handbrake?) to convert to fixed rate.
