Actually, conversion process consists of two parts - decoding/encoding video ( 85%), which is fast, because it uses all 4 CPU's, and creating output file on hard drive (15%), which is not multithreaded process and depends on hard drive speed. As far as I know, our developers have already created some updates to optimize the second part. The updates will be added in the next version of AVS Video Converter and allow to create output file 10-20% faster.


umm, pardon my ignorance re video encoding and the way this program does it, but of the first part is where all the heavy conversions are done, and the second part is where the output file is written (thus so dependent on HDD speed), then how would that suggest multiple hours compared to half an hour for the conversion itself?

Having just bought AVS-VC, I converted a 10GB 1080p mkv to custom AVI/DIVX @ 800x350 (ish) (for mobile phone) with resulting file 1.4GB - I can't imagine how generation of that file could take several hours when the conversion was 35mins.

As for HDD speed, FWIW, this box is ~ 2.6GHz quad-core I5, 4GB RAM, 64bit Win7, and 2x striped 7200RPM SATA drives.

Wierd!! *SOS*

I went through many pages of this forum trying to see of anybody else had this problem, but it doesn't seem so.

Conversion FLYS to around 80%, 2.3 hr movie in 720p in about 20 mins. After that, it takes 30-45 min to do that last 20%. I'm converting for my iPod touch. However, when I'm converting from one HD video to another HD video format it takes an hour to get to 80% then about 2-3 hrs to do the last 20%.

What's the issue? I've tried several different input and output formats. Regardless, it always takes the last 20% about 3 times longer than it took to convert the first 80%.

Intel core-i5 750, 4GB RAM, plently of free HD space.

Thanks.

I have exactly the same issue. It takes almost as long to convert the last part as the rest of the file!

I don't think it's a CPU overheating issue - I've used Speedfan to keep the fans running at 100% throughout - temperature stays down but it still happens.

Convertion process depends on the format and origin of the file you are trying to convert, its size and other parameters, to what format you convert the file to and what settings you select. If you do not display the preview during the convertion, it will take less time.

erobert702:
like its recording 1 frame at a time
sometimes during the convertion several frames are converted without being displayed on the preview window as convertion is faster than playback of the file itself, that is why the program may skip several frames on the preview during the convertion.

erobert702:
this program takes way too long
specify please the format of the file you are trying to convert, its origin and duration, specify to what format you save the file to and how long convertion process takes.

We greatly appreciate your help.

Regards

I am basically having this same issue with conversion.

It seems that if I convert from DVD disc to hard drive I can use the multi-thread stream but it will take a DVD (.vob) 2-3 hrs. The video, mostly, seems to be perfect but the audio is degraded (about 15db to low compared to same conversion above using ac3 codec. The conversion process being used is H.264 AVC 1280x720 30fps 3000 bitrate MP4 PSP and audio is MPEG2/4 (only choice) Stereo 24-bit 48000hz 480kbps. When a blu-ray and/or DVD is converted from hard drive to hard drive, I can only use single thread stream (else all 8 threads on the CPU stay at 100% and raises the core temps up to over 66 degrees celsius) and the conversion process takes blu-ray 4-6 hrs and dvds 2-3 hrs and ending up with the same results where video is good but audio is once again degraded.

My specs for my unit are Intel Core i7-920 CPU 3.6GHz, 6GB Corsair Triple Channel RAM, Corsair H50 Watercooler, ATI Radeon HD5770, Asus P6X58D Mobo, Antec 1200 Tower, XFX XXX-Editrion 800W PSU, and 3 1TB WD HDDs & 3 1.5TB WD (RAID 5) HDDs, and OS is Windows 7 Pro 64-bit.

Hello,

Try using Below Normal priority for conversion in multi-threading mode see the screenshot attached. Perhaps, it helps.

As for audio problem you can apply Amplify audio effect and boost volume level. Here you can find the details how to apply effects in AVS Video Converter.

Regards.

Thank you for responding with the above suggestions. I will give the "below normal" priority a try and see if that helps in the CPU usage in multi-thread. I have notice however, that when converting either DVDs or Blu-Rays, that the video at times seems to be lagging or jagged in areas there there is alot of motion. Any suggestions on how to clean that up and get a smooth flow video from the convert?

Also, I did however already try to use the "amplify" option in the edit mode and it did raise the volume up a tad bit, but I ended up having to try and raise it using the 10db and unfortunately the volume did come up but there is a lot of crackling sounds through out the video especially where there is a lot of bass sounds. Is there any plans in future releases where you are going to provide the option to convert audio using either AC3 or AAC codecs, especially for blu-ray?

Is the video lagging and jagged after converting in both modes? single -thread and multi-thread?

Unfortunately, we do not plan to support AC3 and AAC codecs in nearest future. We are sorry if it may be of any inconvenience. I would also recommend you trying adjust volume in AVS Audio Editor, which can also amplify audio track of video files.

Yes in both threads the video is lagging and/or jagged. Also at times, some of the areas that are really shaded or black/gray are pixelated (Blocky) which for a 1080P quality should never be.

I will give the AVS audio editor a try to see if this might help in the quality of the surround sound.

It is the original video which is 1080p. But as far as I understand you convert it to 480p for MP4. Could you please try converting it to another format MPEG or WMV to see of the same problem with video quality persists?

Regards.

The original source is 1080P and I am wanting to preserve the quality of both video/audio and keep it converted at 1080P. 480P would be no different than regular DVDs. So what would be the use of having blu-ray?

I have tried to also convert into the format of WMV and get the same results. I preferably want to stay with the format of MP4 so that I can continue to stream to my PS3 in my theater room.

Hello,

Could you please specify where do you play resulted videos and they are lagging and jagged? on PS3 or on computer? Please try playing on both and inform us about the results.

Best regards.

After converting any of my videos, I also test them out on my computer first and then just to verify that its not the computer causing the lagging/jagged results, I then test them out on my PS3.

Not only is this happening when converting blu-ray but also if I try to convert a regular dvd to either 720P or 480P I get the same results.

Thanks...

Thank you for the details.

We have tried to reproduce the problem in the same environment, but unfortunately without success.

Could you please send us one of source file which you convert and result of it's conversion with quality problems? I will allow us to reproduce and analyze the problem. The instructions will be given to you in our support system.

Regards.
