Happy to publish our new app. This app is a knowledge hub for the Bronze Drum aka. the Dong Son drum. The Bronze Drum is a kind of ethnic symbolic artifact and art craft in Southern China and South Eastern Asia region.

Announcing completely free e-learning website for digital media production

After nearly a year and still keep going effort, I am happy to announce the Vfxware Interactive Moocs MOOC platform on digital media production. Now the site is free to registrate, free to check course content after registrating. Currently there are 4 courses on site, the major course is the 3D fundemental course I managed with more than 2000 minutes video materials. Current courses are all in Chinese, mainly for my students in the university class, software version I used is in English however.

Arnold reduce preview rendering stuttering issue, and make computer more stable on long renderings

Sometimes Arnold preview rendering in both Hypershad and Arnold Render View cause stuttering issue on my computer with dual cpus and many cores. This is inconvenient for me since I used to record many tutorials for students, Arnold stuttering will stop the voice since all cores are occupied. The fix is acutally very simple, in the System panel of Rendering setting in Maya, uncheck the Autodetect Threads option, and enter a negative number in the Threads block, then it will reserve some computational power, which is good for recording.

Nginx is better than Apache in many ways, however their configurations are very different. A while ago, a friend pointed one of my site cannot be visited without www in the url, it caused trouble, since both and should be redirected to This was due to the web server configuration problem. With apache it should be vhost setting changes, but with Nginx since it uses special syntax, the adjustment is as follows.

Linux shell script batch increases volume for video files with ffmpeg

I recorded lots of tutorial videos for my students using a microphone which is not very nice, so here is an example to batch increase all video files’ volume for 6 db, and export to mp4 files. FOLDER=$1 for i in $FOLDER/*.mov; do name=`echo $i | cut -d'.' -f1`; echo $name; ffmpeg -y -i "$i" -strict -2 -vcodec copy -af "volume=6dB" "${name}.mp4"; done

One Click shooting HDR bracket images with 360 HDR Bracket Tool

Creating HDRI used to be time consuming and require some special equipment, vfx person used to bring heavy ball bearings or big mirror ball on set, and no need to mention that aligning those balls with camera lens axis is nearly impossible, which means it usually ends up imperfect HDRI images produced. Although some expensive controlable platforms designed for DSLR can compensate such issue, making HDRI at much higher resolution, it is still not convinent to do such work.

360 HDR Bracket Tool For Theta App

Welcome to my blog, and thank you for purchasing my app. The 360 HDR Bracket Tool For Theta App I developed is intented to provide a low cost and convenient on set 3D/VFX production tool, working together with a RICOH Theta S or Theta SC 360 camera. This app is capable of shooting multiple 360 images with wide range exposure level settings automatically, which is more than the official Theta App can do.
