Beautiful work David, Sintel looks great when you draw her in 2D. I love the feel of the watercolor. very realistic result. i have to try this technique, maybe when i finish my last piece. again, good work.

by the way, your french voice is not so bad, i heared you on the Viewconference. XDDD lets give it a try

Thanks all !

@Ramon: Hi friend :) Thanks for the encouragement about the english "voice over" , I'm still a bit not confident about , but for sure I need to give it another try and buy a better microphone.

link Steven Powers (SMP)  

Very nice workflow. Tutorial was quick and to the point and the results were very good. I have to agree with Ramon, your voice is just fine. In fact I think by adding your comments into these tutorials, you can convey your methods even more.

Thanks again and Merry Christmas and Happy New Year,

Hi David,

I know you mentioned you used GTK RECORD MY DESKTOP how long did it take to convert (encode the screen recording) tutorial or is there an option to speed this process up I have done a 2 min quick video and its taking about 6/7 Min's before I can watch it back. P.S I have a fast computer system. Also I know you are an artists but I would love to see quick tut on how you use Blender to edit your videos for speed painting / time lapses.

Thanks in advance Steven

link David Revoy Author,

@Numarul7 : Thanks for the timelapse :) As the DVD is in Creative Commons - By ( David REVOY/ Blender Foundation ) this torrent is totally legal, and I'm even happy if their is 6 seeders to share the huge 8Go of content... not easy !
Just for those who want to pay the DVD, remember the money goes to the Blender Foundation and a little part for me each 1000 DVD sold :) It always helps. But I'm always happy to see interest around my Dvd. I'm heaven a bit curious why I haven't seen it yet all the content posted by a user on Youtubes or Vimeo. I shall may be do it myself with the agreement of the Blender Foundation:)

I will continue to watch your tutorials and be inspired by your images ;)


link David Revoy Author,

@Steven : Thanks :) and cool for your message on CGtalk ;)

link Stephane  

Just fabulous!
the watercolor render is like a real one.
I've just seen your two "time-lapse way of working" and I'm very impressive.
You master your subject, no doubt on it ! le "Lezard", c'est juste un truc de ouf ! Chapo !

link David Revoy Author,

Merci Stéphane :)

It would be possible to convert these drawings of MyPaint and Gimp for cmyk mode in Krita ? I have not seen you illustrating in Krita. Cmyk mode is not reliable in this software or is it merely a matter of preference? Thanks David.

link David Revoy Author,

Hi Lisa,
Yes, Krita and CMYKTool are two solution for CMYK convertion. I didn't get the time to test it in depht the CMYK in Krita. The main reason is here I still use my licence of Adobe Photoshop CS2 running with Wine to do a conversion at the end, and some color correction for the printing. This allow me a 100% compatibility with the Adobe design/graphic workflow of my clients.

Excellente vidéo !
tite question sur Mypaint : Est t'il possible de se créer une palette de couleurs pour la dernière version de myPaint? ( j'ai fait des recherches et je suis tombé sur l'Iportnov branch developement qui semble me correspondre à ce dont j'ai besoin mais j'ai l'impression que ça marche plus sur le 0.9).

link REVOY David  

@MrMango : Oui, le code de la palette de la version de Iportnov n'a pas été porté dans le tronc principale de développement ( pour des raisons de mauvaise ergonomie et de propreté du code, il me semble ) et pour l'instant aucune fonctionnalité similaire à l'horizon.

link Itzcuauhtli  

Hi David. Great Job.

Only one question. In witch website is disponible the "Sketch brush pack"? I see that you use in various videos

link David Revoy Author,

@Itzcuauhtli :Thanks ! The 'sketch' brush pack was a experimental group I produced at this time to create a good set of pencils and erasers.
Now, all this brush and erasers are merged in the 2 first row of my brush kit , you can download it here :">
I wish you good painting time with Mypaint ;)

Your link works, but as for the embed, my browser tells me:
> Loading mixed (insecure) display content “” on a secure page 2 video-tutorial-digital-watercolor-with-mypaint-and-gimp

link David Revoy Author,

Thanks! The previous code was trying to embed the video inside my blog, like a media. So, my certificate was mixed with their (Vimeo) certificate. Mozilla was right to tell the content was mixed. I fixed the page by only making a html link to the video. I hope it will fix the issue. Thanks for reporting!
